what is a equivalent way to write 3 times 22 + 3 times 20
A: 5 x 2 (r + 7 = 2 x 5 (r+ 7)
B: 5 + 2 r + 7 = 2 + 5 r + 7
C: 5 divided by 2 r+7 =2 divided by 5 r+ 7
D: 5 - 2 r + 7= 2 - 5 r+ 7
My answer is B

  1. B: 5 + 2 r + 7 = 2 + 5 r + 7

    12 + 2r += 9 + 5r

    3 = 3r

    1 = r

    That doesn't look like 3 times 22 + 3 times 20 = 66 + 60 = 126

  2. I think your answer set doesn't match the question, anyway ....

    3 times 22 + 3 times 20
    = 3(22) + 3(20)
    = 3(20) + 3(2) + 3(20)
    = 6(20) + 6
    = 120+6
    = 126
